IMPROVED EVAPORATlNG-PAN WITH CELLULAR BOILER.

Specification forming part of Letters Patent No. 37,736, dated February 24, 1863.

To all whom t may concern l Be it known that I, D. M. COOK, of Mansfield, in the county of Richland and State of Ohio, have invented a new and useful Improvement in Cellular Boiler and Shallow Evaporating-Pan United for "Evaporating Sushallow evaporator constructed with a cellu-Y lar boiler, which constitutes a portion of its bottom.

Myinventiou also consists in a new arrangement of flame-directors, in combination with the cellular boiler and shallow pan.

To enable others skilled in the art to make and use my invention, I will proceed to describe the same with reference to the drawings.

In order to construct a shallow evaporating-pan with great heating-surface in a small compass, I make the pan-bottom A with a sufficient length and width to evaporate a given quantity of juice in a given time, on an elevated level, as indicated between 1 and 2 in Fig. 2, and the remainder of the pan I construct with deep cells a c, which extend down from the level of the pan-bottom, as represented. These cells are formed by crimp ing or casting metal with folds, and then closing every alternating fold at both ends, thus obtaining cells ad and ilame-flue's hb, as illustrated.

The evaporatingsurface of the pan may be extended from end to end'of the pan and the cellular boiler be within a front and two lateral portions of evaporatingsurlace, as rcpresented in Figs. l and 3.

. The crimps might be diagonal or longitudinal to the passage of the flame, instead of at right angles thereto, as represented. Vhen the crimps or folds are as shown, I arrange amedirectors d d between the ordinary guards, e e, and the front fold, and from these directors extend other diminishing directors, d d', as represented. By this arrangement,

tweenthe cells and walls of the furnace. The

arrest ofthe dame and waste heat by the ce1- lular portion of the pan also causes a greater heat in the pan itself, as the reieeted waste heat is thrown in Contact with the bottom of the pan. Thus, with the same amount of fuel as is used with a pan of the same amount of heatingsurface, but occupying a larger compass, a greater amount of evaporation and a more perfect discharge of feculent matter are effected.

I have shown one of my patented evaporator-pans with the addition of a high ledge. and gate, w x, also a brick fire-furnace; but I do not confine myself to any particular construction of pan or furnace, as it is obvious that the two planes, one shallow and the other deep and with cells, may be embodied in the various evaporators known, and be used with the different furnaces adopted for heating such pans.

The boiler or cellular portion of the pau may be constructed by suspending cylindrical or other geometrical forms of cells from the bottom of the pan. The ame in this case would circulate between and around the cells.

Vhat I claim as my invention, and desire to secure by Letters Patent, is

l. A cellular vboiler and a shallow evaporating-pan united, substantially in the manner and for the purpose described.

2. The arrangement of the directors d d d d', in combination with the cellular boiler and shallow evaporating-pan, substantially as and for the purpose described.

fitness my hand in the matter of my application for patent on shallow evaporatingpan with cellular boiler this 22d day of J anuary, 1863.
